The Magic Sound Of Fenn O'Berg documents the live collaboration of Peter Rehberg, Christian Fennesz, and US ally Jim O'Rourke. Each armed with a powerbook and mixing desk, and usually little prior knowledge of one another´s material or intentions, the results are a stunning flood-and-fold adventure in sound. Of course, the very nature of improv necessitates periods of boredom, false-starts and wrong turns. Yet these excerpts generally witness a trio in staggering form. Whilst all three have delivered superb solo efforts, you get the feeling that it's perhaps the process itself, rather than finalised form that inspires them – twisting and pulling, re-working their sonics, getting off on the “heat“ of live collaboration. Fizzing and flickering, bursting with gritty chatter, all manner of sonic detritus is pushed through the mangler: twinking glockenspiels, bursts of piano, overloading bass drones and frequency-fogs, crumbling traces of pop. Not so much a series of new maps, as a doing away with them altogether, immersing yourself in the freeform thrill of (live) sounds / events unfolding around you. Fucking hardcore.
